Dust Collector Filter Bags are key part of a filtration system. These are made from glass fiber , acrylic , polyester, polypropylene, PTFE, P84 and nomex etc. These pleated dust collection bags are very efficient and offer long-lasting excellent functionality. These pleated dust collection bags are broadly applied for pollution control. Dust collector filter bags are also implemented in metallurgy, fertilizers and chemical companies.
These are essentially required where the dust is generated during processing materials. For instance flour mill, pharmaceutical factories food processing etc, where the dust and some other unsafe elements can not be permitted to exhaust in open environment. Plant of these categories utilize dust collector filter bags to collect dust and other hazardous components. There are a wide variety of manufacturing techniques to manufacture right dust collector filter bags to meet all the requirements of a dust collector depending up on the system of cleaning such as pulse & reverse jet and auto mechanism cleaning.
Advantages of Dust Collector Filter Bags:
1.Its maintenance cost is low.
2.Practical effectiveness of Dust Collector Filter Bags are incredibly high.
3.It recovers heat very effectively.
4.It is effective and not affected by Gas-dust composition.
Dust collector filter bags play an important role in these kinds of manufacturing plants who also produce dust and other harmful chemical crystals with their consumer goods. These industries are such as cement, thermal power station, fertilizers, steel pants , aluminum , zinc , lead , asbestos and chemical plants etc. Dust collector filter bags are utilized here to collect hazardous and dust crystals.
The Secondary objective of the dust collector bags is to check pollution for example air pollution and water pollution. In the cement industry the medium particle size of the cement dust ranges from 8 to 12 microns. When the dust collector sucks the air, air brings with it these elements inside the dust collector. Dust collector sends the air into the dust collector filter bags. Here dust collector filter bags are liable to have sucked crystals and permit the air to pass. In all the stages of cement manufacturing , dust collector filter bags are proved to be the best because of its high-efficiency and flow rate etc. Dust collector filter bags may work proficiently during working in various temperatures, which may differ in accordance to the process of manufacturing dry or wet in production plants in the range of 150 degree Fahrenheit to 250 degree Fahrenheit.
Types of Dust collector filter bags:

A.Acrylic homopolymer needle punched filter felt:
Acrylic homopolymer needle punched filter felt are provided in woven or felt form. This product delivers hydrolysis resistance identical while allowing operation up to 250 degree Fahrenheit (equivalent to 121 c).

Its feature is the Best combination of filtration efficiency and dust layer release.
It provides good hydrolysis resistance.
It is utilized in chemical processing .
It is implemented in mineral processing.
It is employed in metal processing.

B.Antistatic Needle Punched Filter Cloth:
Anti static needle punched filter cloth simply results in the explosion and conflagration after the consistency of common commercial power and dust reaches certain degree. It is handling the static electricity light and spark outside such as flour powder, coal powder and chemical particles. To have fine particles of dust the filter medium of bag must be anti static.





C.Aramid Needle Punched Filter Cloth

The characteristic of aramid filer needle felt is high temperature (between 200 ~ 220 degree), after some special finish treatment, anti acid ,anti alkali , high filtration precision ,low pressure drop and anti break .Its some other characteristics are anti abrasion, mostly applied in pitch mix gas, blast furnace gas of steel factory , tail gas of while char, kiln application in cement plants and electrical cooker high temperature gas in the other plants,etc.

D.P84 Needle Punched Filer Felt:
P84 needle punched felt is a extreme temperature proof filter material good chemical proof, good air permeability and high filtration performance. It is mostly used in coal boilers of thermal power stations.

E.Polyester (PET) Needle Punched Filter Felt:
Polyester needle punched filter felt provide a cost effective option for several industrial activities. They are highly adaptable and efficient in dust collection.

F.Water and Oil Resistant Filter Cloth
After oil and water treatment several filter fabrics can form a layer of molecules blockage around the fiber surface. This type of dust collector filter bags filters different pollutants from the water and oil.

G.Filter Bags with PTFE Membrane Laminating-

These dust collector filer bags are employed in all the dust collector applications. The expanded PTFE Membrane permits more air to pass through the filter media while trapping particles on the surface. Using this form of dust collector filter bags engineers can reduce capital and operational costs. Use of this style of dust collector filer bags also present a degree of protection from the unknown and indirect-able changes that sometimes occur during bag house operations.

Other types dust collector filter bags are:

1.Glass fiber Needle Punched Filter Felt

2.Poly-P-Phenylene Sulfide(PPS) Needle- Punched Filter Felt

3.PTFE (Polytetrafluoroethylene) Needle Punched Filter Felt
